What is the function of the copper coil in the appliance?
This inductance is called inductance (self-inductance), which is the property of the closed loop itself. Suppose that the current in a closed loop changes and the electromotive force is generated by induction, in another loop, called inductance (mutual).
Inductance: an inductance is a property of a closed loop, i.e., an electromotive force is introduced to resist current changes when the current in a closed loop is changed.
Inductor: (Inductor) a component that can store electrical energy into magnetic energy. The inductor is similar in structure to the transformer, but has only one winding. An inductor has a definite inductance, which only blocks the change of current. If the inductor is in the state of no current passing through the circuit, it will attempt to block the current flowing through it; if the inductor is disconnected when the current is current, it will attempt to maintain the current. Inductor, also called choke, reactor, dynamic reactor.
